Clean up synonyms File, Email, Item etc

[xecrets]

When parsing arguments the first argument has a lot of synonyms, which are then propagated as separate things throughout the code in Status and Parameters. In the end, it's just confusing and a lot of duplicated data in the end sent in CliMessage. Remove synonyms and use for example Item1 and Item2 instead, and let the context determine the semantic of the item, if it's a filename or an email etc.
